% The position vectors, gravitational parameters and velocity for the planets.
The frame is heliocentric, i.e. xy-plane is the mean earth's orbital plane.
This function uses persistent variables to store the planet elements
obtained from Planets during the initialization call.
You may use EITHER multiple planet IDs OR multiple dates when using this
function, but not both.
--------------------------------------------------------------------------
Form:
[r, mu, v] = PlanetPosition( action, d )
PlanetPosition( 'initialize', ids )
[r, mu, v] = PlanetPosition( 'update', jD )
--------------------------------------------------------------------------
------
Inputs
------
action (1,:) 'initialize' or 'update'
d (1,n) Julian date (days) for update or planet ids (1-9) for
initialize
-------
Outputs
-------
r (3,n) Planetary position vectors
mu (1,n) Corresponding gravitational parameters
v (3,n) Velocity vectors
